Key Differences between Roomba 614 vs 620 vs 650

Cleaning Performance. When comparing Roomba 614 vs 620 vs 650 in terms of cleaning capability, the 650 wins by a slight margin. They may be equipped with the brand’s 3-stage cleaning system, but the latter has much more to offer. A good example would be its auto-detection of any large obstacles along its way. It simply makes the cleaning faster and runs smoother. When it comes to usability on different surfaces, the 614 is good for pet hair, a variety of carpets, and hard floor surfaces, while the 620 Roomba model is intended for carpets, tile, also hard floors, and laminate.

Design. Although these models have major similarities in design, the latter was more preferred as can be seen from customer reviews. It has a better color scheme, which is a little surprising since it makes use of a single color, black. In terms of functionality and button placements, they are 99% similar. Both can blend well with any room designs.

Navigation. This is considered to be the defining difference between them by a lot of review sites. They both are equipped with iAdapt Navigation system, but somehow the Roomba 650 has a better AI or Artificial Intelligence. The 620, however, has a Dirt Detection feature that is programmed to look for dirtier places.

Battery and Power. The 614 and 620 model might have longer-lasting batteries, but it has to be recharged manually. The 650, on the other, hand features an automated docking system where it recharges itself without the help of a user.

Roomba 620 Review

The iRobot Roomba 620 mostly has the features a Roomba product has to offer. It is installed with AeroForce 3-Stage Cleaning System and Virtual Walls Technology. Both features that significantly improved the cleaning capability of this robotic device.

The most acknowledged and praised feature of the 620 is how easy it is to operate. There’s no need for programming and most importantly, no heavy maintenance required. It’s as simple as pushing a button.

Pros

3-Stage Cleaning System.

Dirt Detection Technologies. It is an efficient feature that can prioritize places that needs more cleaning.

Roomba 650 Review

The model has a couple of features that really stand out among its competitors. Aside from its 3-Stage Cleaning System and Virtual Wall Technology, the device also has an Auto Docking System.

Just these three features already put this device on top of the list among cordless vacuum cleaners. It may not be the best out there, but it certainly is one of the good ones. That is, of course, considering its release was several years ago and it still is a relevant product in the vacuum industry.

A few more notable features this device has to offer are its Scheduling Function, Auto-Recharge and Resume, and Auto-Floor Adjustment System. Features that can really help make the cleaning easier and hassle-free.

Pros

It has an automated recharge system that will do them by itself.

The scheduling system.

The technology that automatically adjusts itself in cleaning different types of floors.

The device has a well-made attractive design.

Cons

The sensors randomly pick areas to clean.

Similar to the 620, it does not support remote control functionality.

Our Verdict

When talking about the overall performance of each device, there is no denying that the iRobot Roomba 650 has much more to offer. Aside from the cleaning capability advantage, it is much easier to operate. Scheduling may take a little programming for it to work but that’s about it.

These two cleaners come from Roomba’s 600 series are priced around the same amount. In terms of features, the 620 seems lackluster compared to that of the 650.

It really is a big factor considering that some users don’t have the extra time to manually maintain the operation. These are the types of differences that can be a deciding factor for potential customers.

If you can afford a much higher priced robot vacuum cleaner, we recommend you to check out the more current Roombas or other cleaning products. They offer better features and are more effective in cleaning.
